ensure that the proper number of arguments are being passed

You'll have to do this with regexes because people usually have spaces in quotes and weird stuff like that. Only do this check if the flag is present. If it is compliant with the regex, continue; if not, break.

Possible forms:

alias pies='commands and stuff'
addalias limes="more commands"
alias 'dadhats'="do stuff"
addalias "snapbacks"='wow this is exciting'

Structure

call: lower/upper alphabetic space: at least one nickname: bookended by matching ' or ", lower/upper alphanumeric and underscore =: match identically commands: bookended by matching ' or ", some combination of any characters (.*)

Edge cases to be concerned about:

• What if quotes are in the commands?

Figure out:

How do you use k regex anyhow?

Now that we are using the altalias strategy as referenced in #46, things have changed.

• [x] What happens if alias can't handle what it's given? It should echo out an error message. That's okay.
• [x] What happens if an alias is not able to be defined and we barrel ahead and expect alias to give us an output we can write to .usr_aliases? What will alias return and what gets written to file?

I put garbage in and it says:

1
-bash: alias: erwiojgklelkmw: not found
Creating new permanent alias: alias aha='new command'

Then it dumps the current aliases into the terminal, which isn't, like, awful. (I need to get rid of that number, btw, wherever that's coming from, and I don't know what permanent alias it's trying to make with aha='new command'.)
